\ "imi- 3111111111111111 L M Afr/l1 INVENTOR Hag/r 57cm WW Patented Dec. 31, 1935 UNITE STATES T OFFICE ONE PIECE DOUBLE EDGE RAZOR Harry Blau, Brooklyn, N. Y. y Application July 12, 1934, Serial No. 734,741 1 Claim. (Cl. 30-56) The purpose of this invention is to provide a one piece double edge safety razor, that is, a safety razor in which all of the parts are connected with the exception of the blade, in which the blade is held against a frame forming the cap by a nut at the end of the handle, and in which the blade may also be released by the same nut.

The invention is a double edge safety razor in which the guard is mounted upon a rod extending thru the handle and the blade is placed upon the guard and held against the under side of a frame in the form of a yoke extending from the end of the handle and forming the cap. The guard is operated by the rod extending thru the handle to secure the blade in the cutting position and also to release the blade so that it may readily be removed and replaced.

Safety razors have been made of many different types and in many designs, and many designs of one piece razors have also been provided. Safety razors are distinguished as one piece razors when all of the parts with the exception of the blade are hingedly or pivotally connected so that the guard, cap and handle are connected together to form a complete unit, and either part cannot be misplaced or separated from the others. These razors have been provided with the cap hinged to the guard and with the blade secured between the cap and guard, however, in substantially all razors of this type the guard is drawn downward against the blade by the handle extending thru the blade, and it has been found desirable to provide means for securing the blade against the guard without eX- tending the connecting means thru the blade.

The object of this invention is, therefore, to provide a safety razor of the one piece type in which the connecting means does not extend thru the blade.

Another object is to provide a safety razor of the one piece type in which the head of the razor is provided in a frame in the form of a yoke extending from the end of the handle.

Another object is to provide a safety razor of the one piece type having a frame at the end of the handle in which means is provided for frictionally holding the blade against the inner side of the frame.

A further object is to provide a safety razor of the one piece type having a frame at the end of the handle in which the blade may be rigidly held on the inner side of the frame by an operating member at the end of the handle.

And a still further object is to provide a safety razor of the one piece type in which the blade is held in a frame at the end of the handle which is of a simple and economical construction.

With these ends in View the invention embodies a safety razor having a handle, a frame extending in the vforrn of a yoke from the end of the handle, a guard inside of the frame rigidly attached to a rod extending thru the handle, means locating a blade on the guard, and means at the end of the handle. adapted to operate the rod to move the guard and blade upward and secure the same against the inner side of the frame.

Other features and advantages of the invention will appear from the following description, 15 taken in connection with the drawing, wherein:

Figure l is a view showing a side elevation of the razor.

Figure 2 is a view showing an end View with part of the handle broken away and with the guard shown in dotted lines in the position in which the razor blade may be removed and replaced.

Figure 3 is a plan View showing the guard and razor blade in th'e transverse position, from 25 which the blade may be removed and replaced.

Figure 4 is an end view of the frame and upper part of the handle with the other parts removed.

Figure 5 is a View similar to that shown in Figure 1 with the guard and blade shown in the 30 transverse position.

Figure 6 is aview showing a cross section thru the razor with the guard extending across the razor and with a blade shown held between the thumb and forenger, and as it would be inserted in the razor.

Figure '7 is a cross section thru the lower part of the handle showing means for raising and lowering and turning the guard as it is raisedv and lowered. 40

Figure 8 is a similar view showing an alternate means for raising and -lowering and turning the guard.

In the drawing the razor is shown as it may be made wherein numeral l indicates the handle, numeral 2 the guard, and numeral 3 a razor blade that may be held upon the guard.

The handle l may be of any type or design, may be of any shape, andany means may be provided therein for holding the guard at the upper end and also for operating the guard from the lower end. In the design shown, the central part of the handle is made of a somewhat rectangular shape with the corners rounded and with recesses formed in the sides thereof. At the upper end straight downward, so

of the handle is a frame comprising a lower bar 4 having upwardly extending ends 5 and 6 and a horizontal portion 'I at the top forming a cap, the shape of which is similar to the cap of a safety razor. It is preferred to make the ends 5 and 6 of a somewhat circular shape, as shown in Figures 2 and 4, however, it will be understood that these ends may be of any shape or design. It will also be understood that any other means may be used for connecting the ends of the cap 'I to the end of the handle around the ends of the guard 2.

The guard 2 is similar to a safety razor guard having teeth 8 in the edges thereof, and the upper surface is provided with pins 9 adapted to be inserted in the ends of an opening IBA in a razor blade, as shown in Figure 3, however, it will be understood that any means may be provided on the guard for locating and holding the blade, and an opening or openings of any type or design may be provided in the blade.

In the design shown the guard 2 is rigidly attached to the upper end of a rod I I, which extends thru the handle and is connected to a nut I2 at the end of the handle. This rod may be connected to the nut in such a manner that as the nut is rotated in one direction, the guard and blade will be lowered from the position shown in Figure 1 to that shown in Figure 5, and both the guard and blade will then be turned to the transverse position, as shown in Figure 3, and also as shown in dotted lines in Figure 2, and when the nut is turned in the opposite direction, it will rst turn the -guard and blade to the longitudinal position, or parallel with the frame, and then raise the guard and blade until the blade is frictionally held or clamped between the upper surface of the guard and the under surface of the cap 1. The cap 'I may be provided with recesses I3, as indicated by dotted lines, into which the upper ends of the pins 9 may extend, as shown.

In the design shown in Figure 8, the rod II is formed in two pieces connected by a coupling I4, withV the lower end I5 attached Vto a threaded shank II on a nut Il at the lower end of the handle, which is indicated by the numeral I8. It will be noted that as the nut I'I is screwed outward and inward, it will move the guard 2 upward and downward thru the rod II. In this design the rod` Il is provided with a pin I9, which eX- tends into a groove 20, and it will be noted that this groove will permit the pin to; rst move that the guard 2 will be lowered from the cap 7, and then, as the rod II continues to move downward, the pin Il? will follow the slot 20, so that the upper part of the rod` will befturned thru a quarter of a circle. It will be understood, however, that any other means may be provided on the rod for engaging parts in the handle to cause the rod to turn as it kis drawn downward and return to the same position as it moves upward.

The design shown in Figure 7 is similar, except that the rod, which is indicated by the numeral 2|, is provided with threads 22 at the lower end, which screw into an opening 23 in a nut 24 at the lower end of the handle, which is indicated by the numeral 25. In this design, the rod 2| isprovided with pins 26 that extend outward into grooves 21 in the sides of the handle 25,

and it will be noted that as the nut 24 is turned in one direction, it will rst draw the rod 2l downward and, as the pins 26 follow the grooves 2l, they will cause the rod and nut to turn thru a quarter of a turn so that the rod, with the guard 2 on the upper end, will turn and move the guard to the position as shown in Figure 3. Then, when the nut is turned in the opposite direction, it will move the rod upward and, as the rod starts to move upward, it will first turn the guard to the longitudinal position, .and then raise the guard so that a blade positioned thereon will be held against the under side of the cap l. It will be understood, however, that any other means may be used for moving the rod and guard upward and downward, and these may be operated thru the handle, or by any other means.

It will be understood that other changes may be made in the construction without departing from the spirit of the invention. One of which changes may. be in the shape or design of the handle, another may be in the use of a cap of any other type or design or of other means of holding the cap to the handle, another may be in the use of other means for locating and holding the 'blade on the guard, or in the use of a guard of any other type or description, and still another may be in the use of other means for `operating the guard thru the handle.

The rconstruction may readily be understood from the foregoing description. In use the razor may be provided as shown and described, and it will be noted that withthe parts arranged in this manner the guard 2 may be turned to the transverse position so that it will extend across the frame, and the blade may be inserted under thecap 1 and placed upon the guard with the opening therein over the pins 9, and then the guard may be turned lengthwise and raised with the blade held against the under surface of the cap 1. The razor may then be used in the usual manner, and when it is desired to clean the same or remove the blade, the guard is lowered `and turned' sothat it extends across the frame and the blade may readily be removed therefrom. This device, therefore, provides a complete one piece razor with' all of the parts substantially enclosed in al'frame on the end of the handle.

Having' thus' fully described the invention, what I claim as new and desire to secure by Letters Patent, is:

As an article of manufacture, a safety razor having a. cap, a guard, a handle to which the cap is permanently attached by side members forming a yoke, the guard being located within said yokeY and below said cap, a shaft by which thel guard is carried pivotally mounted in said handle and Xedly attached to said guard, means adapted to rotate said shaft and additional means by which said shaft may be moved lengthwise of 'said handle, permitting turning thereof, to turn Ysaid guard to a position crosswise of said yoke,

and'Y means adapted to locate a blade on said guard, said yoke providing suiiicient clearance for the guard to move downwardly away from said cap, `and the' end members permitting the guard'to swing to a position transversely of the cap to enable a razor blade to be placed thereon and removed therefrom.A l
